    No luck in the repair thread. Thought I would try here.
    I have a 19HP Kawasaki that I would like to keep the carb in clean condition. Would it be a good idea to run a product like Sea Foam through the tank at every oil change? (50 hrs) If so, How much do I add to a gallon of gas? The directions are not clear as to how much needed to clean the carb Just says "add more to clean" and gives a very wide range or oz per Gal. (like 3 to 21oz)
    What do you use and how much?
    Also I have Sea Foam in a spray can. Boy does it make the engine smoke. does it help to clean the carb by just spraying in the carb as the engine is running???

    Hmm....How about old school style, clean fresh gas, tight fuel cap, and routine maintenance? Change the air and fuel filters regularly and you SHOULD be fine. Dont bother with that other stuff. -Rich

    Rich is right but if you do think you sucked some dirt in the carb another old school method of cleaning is to take the air filter and shroud off, run engine full speed,cover air intake with rag or hand till engine almost dies and release,repeat if necessary,should suck the dirt right out.

    Use Sea Foam usually twice a year. Once during the summer and once during the winter. It goes into all of the equipment at 1.5 oz per gallon of gas. I don't know if it really makes much difference, but I feel better having added it.

    I hear what you are saying but am looking at this as a preventive maintenance or "insurance" to keep things clean. We all should eat right and exercise but pop a pill for high cholesterol. same sort of thing. No matter how much we try over time the carb will get dirty.

    hate to tell you guys, but the idea for spraying carb cleaner into the intake, does nothing but clean down any build up on the throttle butterfly.

    The only way to clean a carb is to remove and disassemble it.

    I have people come in all the time......my machine won't start, it's been sitting for a year, think it's the carb? YUP.

    Ok, i'll spray some carb cleaner on it..

    It's like putting a bandaid on your stomach for a ruptured spleen.

    I agree that once a carburetor is clogged or not running correctly the only real repair is to pull the carb. and clean it out.

    This being said, I fully endorse the use of Sea Foam in both your fuel and oil (read instructions). Very helpful in reducing carbon deposits, cleaning intake valves, etc. Not a cure all but helps prevent future problems. Especially with the poor quality of fuel being sold to us here in the US these days.

    Any special tips on complete disassembly then? (KAW 13HP) Or is it just a matter of taking it off & piece by piece?

    If you're not having a problem don't touch the carb.

    I like to add some fuel injector cleaner to the gas once in a while myelf.

    on two-cycles i watched the exhaust port when i shut off the trimmer (the muffler off) and the fuel poured out all around the walls where the carbon builds up. the other day i cleaned the exhaust port it was gooey cause it didnt have enough time to dry and get brick hard yet. so i turned the trimmer on its side and poured seafoam in it with the piston all the way up. in a couple of minutes i flipped it over poured the seafoam out and EVERY SPECK of the gooey carbon had vanished. so i THINK so far unless i get proven other wise that if you use seafoam as a fuel additive in your 2-cycle can it will probably keep them clean for an extremely long time or it will never build up carbon at all if you ALWAYS use it.
